At least two polymorphic markers per gene (rs1718031 and rs729386 for NPHP1; rs1041480 and rs2064430 for AHI1; rs2061589 and rs1508595 for CEP290; rs1990637 and rs1946155 for RPGRIP1L; rs1483457 and rs911 for TMEM67) were inconsistent with linkage in Ciliopathy-672. This evidence concerns the gene NPHP1 and ciliopathy.
